HENRY A. soHU'rr AND CHARLES rpronnnruvr, or GRAND RAPID-S, MICHIGAN.

r CARBURETER.

Toall may concern: y

\Be it knownthat we, HEN Y A. ScHU'rT and CHARLEs FLFORDHAM, citizens of the United States, residing at Grand Rapids, in

thecounty of Kentandstateof Michigan, have invented certain new and useful Improvements in Carbureters, of which the following is a specification. l a

Our invention relatesto improvements in appliances forproducing an explosive by mixing air withhydrocarbon vapor, and its objects are: first, to provide a means whereby the hydrocarbon, as gasolene, will be reduced to the highest possible degree of vaporization while still in the containing tank;' second,to provide av means whereby the amount of hydrocarbon iiithecjoritaining tank may be held uniform; third, to provide a means whereby the exhaust of gas from the containing tank to the engine may be automatically cut off when the supply of hydrocarbon to the containing tank exhausted, and, fourth, to provide a means whereby the mixing appliance may be readily removed from, or replaced into the containingtank. l

7 We attain these objects by the .--mechanism'illustrated in the accompanying drawing, in which l igure 1 is a vertical section, partly in perspective, of the containing tank and its several elements 2 is a vertical section of the lowerend of. the tankshowing the air passage into the distributing chamber. Fig. 3 is a sectional view of the gas discharge side of the tank practically on the line 33 of Fig. 1 showing the valve and ports for regulating the discharge of gas from the tank into the engine cylinder, and, Fig. 4: is a plan of the floor of the tank showing. the perforations through which air is made to pass into the distributing chamber and thence through the pipes to the open tank.

Similar numerals indicate similar parts throughout the several views.

This carbureter, or, more properly speaking, this mixer is made up of a container tank, 1, the bottom and end walls of which are made double to form the flues or passageways 8, 9 and 11, and the inner wall of the, relatively, left hand side of the tank passes far enough down in the tank to form a dam or wall at 26 to prevent air from being drawn out through the flue 11 into the gas distributing cvlinder 3.

The air distributing mechanism in this Specification of Letters Patent. Patented Sept 16, 1919 Application filed May 20, 1918. Serial No. 235,724;

mixer consists of an inverted pan 5, which is placed in the bottom of the tank 1, in such a position that it covers the perforations 10,

sothat any air that is drawn through the receivlng cyllnder 2, into and through the fines 8 and ,9. will pass through the perforations 10into the inverted pan 5, and thence through the pipes 6, which open into the pan 5 at 7, and out of these'pipes into the main body of gasolen'e127. Bythis means the air-enter ng arrange "the cylinder 2 is made to forc'ethe gasolene out of the flues 8 and ,9 into the main tank 1, and to pass through gasolene from the openings 10 and thepipes 6 andto the surface of the gaso- The (inflow of gasolene througlithe pipe 21 is governed by an automatically operated valve 22 as follows: Anangled lever 25, 25 is pivotally supported in the tank, as at 2 1, and has'a float 23 upon the jfree'end of the lever 25,- so set that when the gasolene has raised to a certain height in the tank 'the'fioat "will be raised upward until fthe valve will be So"'cl0sely setngainst the inner end i of the pipe to whollyshut off the flow of gasolene,orany other liquid, through "the pipe 21 into the tank 1.

The outflow of gas from the tank through the carbureter 4: is governed in like manner. That is, a valve 16 is placed in position, as in the slides 18, to be readily made to move upward and cover the port 19 and prevent gas from passing through said port and out through'the port or openings 19. This action of the valve 16 is brought about automatically, as follows: When the tank is well filled the float 12 is raised sufficiently to move the valve 16* from over the port 19, and when the liquid is well exhausted the weight of the float 12 will be suflicient, acting through the lever 1415 over the ful crum rod 13, to force the valve to slide u-pward over the port 19, and thus shutoff the current of gas from the tank into the en gine cylinder, through the distributing cylinder 3 into which the ports or openings 19 open.

The cylinders 2 and 3 communicate with the flues 8 and 11 by means of a port 19 from each cylinder into its respective flue. The holes 17 mdicate a convenient means for connecting the ends of the lever 15 with carbon vapor, a containing tank having the end walls and the floor made double to form a flue at each end, and at the bottom of the tank, an air receiving cylinder, and a gas distributing cylinder communicating w1th sa1d end flues, the lnner wall of the bottom of the case being perforated for the passage of liquids and air, an inverted pan over the perforations, and air conducting coils connectedwith the bottom of the pan and opening over the perforations in the floor wall of the tank.

2. In a device for mixing air with hydrocarbon vapor, a containing tank having the end walls and the floor made double to form a flue at each end, and at the bottom of the tank, an air receiving cylinder, and a gas distributing cylinder connected with the tank and communicating with the fines in the end walls, the upper Wall of the floor being perforated, an inverted pan resting on the floor over the perforations, tubular coils connected with the pan and opening over the perforations and arranged to open into the liquid contents of the tank below its surface, an inflow pipe, and a valve and float to control the inflow of liquid to the tank.

3. In a device for mixing air with hydrocarbon Vapor, a containing tank having the end walls and the floor made double to form a flue ateach end, and at the bottom "opposite side of the tank, a liquid inflow pipe, a valve connected with said pipe and controlled by the level of the liquid in the tank, and a valve made to slide upwardly and downwardly by reason of the raising or lowering of the liquid in the tank, the side of the tank back of this valve having an open port for the free flow of vapor into the vapor distributing cylinder.

l. In a device for mixing air with hydrocarbon vapor, a containing tank having the end Walls and the floor made double to form a flue at each end, and at the bottom of the tank, the floor having perforations opening from the flue into the tank, means for ad mitting air into the tank through the flue in the walls and the floor, a removable conductor pan and tubular coils, a pipe for admit ting liquid into the tank, means for automatically controlling the flow of liquid through the pipe, a means of escape for gas from the tank, and means for automatically regulating the outflow of gas.
